You can perform the following general checks:
Check whether all cables have been correctly connected.
Check whether the current sensors have been installed around the correct phase wires.
Check whether the current sensors have been installed in the correct direction around the phase wires.
Check whether the voltage branches are installed on the correct phase wire.
Check whether the wires of the voltage branches are connected to the correct connector on the DAQ.
Power Supply Check
Power Supply Check
You will find one LED indicator on the power supply adapter that has been labeled DC OK. It will light green if the power supply has been connected correctly and receives sufficient power.
DAQ Check
DAQ Check
There are two LED indicators on the DAQ, as shown in the image below. LED 1 specifies data-related conditions, and LED 2 specifies motor-related conditions.
If LED 2 emits red light: The connector of at least one current sensor does not have a proper connection to the DAQ. Check whether the connector is properly connected to the DAQ and the cable set, and power cycle the DAQ by disconnecting and reconnecting the network cable.
If LED 2 lights green: All current sensors are correctly connected to the DAQ, but this does not indicate whether the phase order and current sensor orientation are correct.
When the DAQ is on, LED 1 will light green. LED 1 can take the following actions:
If LED 1 flashes white: The DAQ is processing data and forwarding it to the gateway.
If LED 1 flashes green: The DAQ connects to the gateway, but the gateway can't connect to the DAQ. Please check the cable with a cable tester.
If LED 1 flashes blue during boot: This is normal behavior. However, if it stays blue, the DAQ may need replacement.
If LED 1 flashes red: The DAQ cannot find the gateway. For this scenario, please check the cabling from the switch to the gateway first, followed by the cable between the DAQ and the switch.
Switch Check
Switch Check
If the switch operates correctly, the PW1 and/or PW2 LED will be steadily green, and the LNK LEDs of all Ethernet ports in use will be blinking green. If Power over Ethernet is being used, the yellow POE for that Ethernet port will be lit.
Notice: If only one of the two power ports is connected, RLY will light up red, which is not an issue.
Gateway Check
Gateway Check
There are 3 LED indicators on the Fitlet gateway, as shown in the image and table below. Here’s an explanation of the different scenarios related to different LED combinations:
If the gateway is operating correctly, LED 1, LED 2, and the Fitlet LED will be continuously green.
If the Power LED is off, the gateway is not receiving power:
Check whether the connection is firmly pressed into the gateway.
Test the installation wire using a certified multimeter. To achieve this, position one probe of the multimeter into a connector of the power supply and one into a random port of the gateway to check for continuity.
If LED 1 is not on, the cloud connection has been interrupted. In this case, reset the gateway by disconnecting it from the power supply adapter and the switch. Reconnect the gateway after the LEDs have been off for 10 seconds.
If LED 2 is lit up yellow, the wireless signal strength is insufficient. Try repositioning the magnetic foot antennas to increase the signal strength. If this doesn’t work, add a second antenna or try a wired connection. For more information, see steps 7 and 8 of the SAM4 Setup Tool.
